    [cairo-xlib-screen] Clear the gc_needs_clip_reset after use.
    
    After consuming the GC we need to unset the clip reset flag, so that
    if we try and get a new GC without first putting a fresh one we do not
    try to call XSetClipMask on a NULL GC.
    
    (Fixes http://bugs.freedesktop.org/show_bug.cgi?id=10921)
